SlideShowExtender on MasterPage

Question

User1856414974 posted

Hello!

I'm very new to AJAX but I wanted to put a slideshowextender on my master page and at the same time load automaticaly the files from a specific folder. 

I got this code on my WebServices:

<WebMethod(true)> _
    <System.Web.Script.Services.ScriptMethod> _
    Public Function GetSlides() As AjaxControlToolkit.Slide()
        Dim NomeImagens As String() = Nothing
        Dim Caminho As String = ""
        Try
            NomeImagens = System.IO.Directory.GetFiles(HttpContext.Current.Server.MapPath("~") & "Imagens\Parceiros")

            If NomeImagens.Length = 0 Then Return Nothing

            Dim Imagens(NomeImagens.Length - 1) As AjaxControlToolkit.Slide

            For i As Integer = 0 To NomeImagens.Length - 1
                Dim Ficheiro() As String = NomeImagens(i).Split("\")
                Imagens(i) = New AjaxControlToolkit.Slide(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) & "/Imagens/Parceiros/" & Ficheiro(Ficheiro.Length - 1), Ficheiro(Ficheiro.Length - 1), "")
            Next
            Return Imagens
    End Function

And this code into a Div:

<asp:Image ID="image1" runat="server" Width="100%" Height="100%" />
                           <cc1:SlideShowExtender ID="SlideShowExtender1" runat="server" TargetControlID="image1" ContextKey="~\Imagens\Parceiros\" AutoPlay="true" Loop="true" SlideShowServicePath="~/WebServices/WebServiceImagens.asmx" SlideShowServiceMethod="GetImages"></cc1:SlideShowExtender>

It doesnt work at all. I made a new project but instead of using it on a masterpage a used a WebForms and that worked. Is there something I'm missing to have it working on the master page?

SlideShowServiceMethod="GetImages"

Not sure if this is a type, but You have your method name in WebService declared as GetSlides and in the SlideShowExtender you are using GetImages method. Try changing it to GetSLides like below

<asp:image id="image1" runat="server" width="100%" height="100%" />
<cc1:slideshowextender id="SlideShowExtender1" runat="server" targetcontrolid="image1"
    contextkey="~\Imagens\Parceiros\" autoplay="true" loop="true" slideshowservicepath="~/WebServices/WebServiceImagens.asmx"
    slideshowservicemethod="GetSlides"></cc1:slideshowextender>

Hi Batto,

Batto

Public Function GetSlides() As AjaxControlToolkit.Slide()

Batto

SlideShowServiceMethod="GetImages"

Firstly, as a2h said, please make sure if the name of your slideshowservicemethod is correct.

Secondly, you could set breakpoint in your WebServices method to check if the method could be called by slideshowextender.

Oh I took notice of that as I posted this post, I fixed it but it still doesn't work. I tried debugger but somehow it doesnt "pass" there.

This also shows sometimes but I've changed the ID's and it still keeps doing that. If I comment the one he's giving error he just goes for the next one.

Hi Batto

                 The error states that you are using multiple Ajax control toolkit Toolkitscriptmanager tags in your page. There is no need to use multiple toolkitscriptmanager tags while using Ajax control toolkit controls. Remove extra tags.
